Q.1 A coil having n turns and resistance RΩ is connected with a galvanometer of resistance 4R Ω. This combination is moved in time t seconds from a magnetic field W1 weber to W2 weber. The induced current in the circuit is
  $\frac{W_{2} - W_{1}}{5Rnt}$
  $-\frac{n\left (W_{2} - W_{1} \right )}{5RT}$
  $-\frac{\left (W_{2} - W_{t} \right )}{Rnt}$
  $-\frac{n\left (E_{2} - W_{2} \right )}{Rt}$
